ELECTRIC LoooMo'rIvE.

Application led September 24, 1927. Serial No. 221,660.

This invention relates to electric locomotives and moie particularly tolocomotives of the small storage battery type used in met-al mines,commonly known as trammers.

Locomotives of this type are adapted for use in metal mines, in whichshafts are small and the locomotives are lifted or skipped from onelevel to another. For this purpose the locomotive must be ofcomparatively lo small dimensions, particularly as tolength, andaccordingly, it is desirable to provide means for removing or otherwisedisposing of the end cab in order to load the locomotive into the cage.a

The principal object of the present invention isto provide alocomotiv ofthe tramming type having an improved means of disposing of the motormanscab when necessary,r and of controlling the locomotive, whereby thecontroller drum is actuated remotely therefrom, and a safety featureprovided thereior, whereby the controlling means is locked w en the endcab is in the inoperative position.` My invention may be best understoodby reference to the following drawings, wherein: Figure 1 is a sideelevation of a locomotive embodying my invention, showing the end cab ininoperative position in full lines and in the extended, or operative,position in dotted lines, with parts of the former broken away to showdetails of fh/egearing; 'j Figure 2 is aplan top view of the locomotivewith the battery box removed and showthe end cab .in extended position;and Figures 3 and 4 showdetails of the conrolling device and the lockingmeans thereor. i i Y Referring now to the details of the ldraw*- 49intgfl have shown a locomotive 10 having frame bar members 11, 11,affording support for the battery box 12, which `may be clamped thereonin an well-known manner.` Supporting wheels an axles 13, 13, and 14,

t5 14, respectively, supportvthe locomotive on the track rails. Atelescoping end cab is generally indicated at 15. A laterally disposedcontroller'of the usual type is indicated at 1 6,

. having the usual contact shaft or drum 17 thereon.` f ,v 5, i.. -Amotor 18 is provided vfor propelling the locomotive. i Details of thedrive gearing and electrical connections to the motor 18 need not vherein be described, as they form no part of the present invention,excepting to point out the additionallength afforded by a motor pinion19meshing with a spur gear 20 keyed to alongitudinal drive shaft`21 supported in `bearing housings 22, 23, on the axles 14.- twin. bevelpinions 24, 25, meshing respec-` tively with bevel gears 26, 27, keyedto each of the axles for driving the same. l,

The end cab 15 comprises a substantially rectangular portion having anend wall 4U, side walls 41, 41, and a-base vor bottom plate 35. Barsupporting kmembers or extensions .assIGNon To GoonMAv MANUFACTUR- Ateach end of said shaft 21 are keyed 45, 45, are riveted to the sidewalls 41, 4l, of-

the end cab, being curved to form shoulders 42, 43, and therefromextended further to 'register slideably with the barV frame mem. bers11, 11, through suitable guides 44, 44, Stops 38 of the/usual blockconstruction are connected to the extension 45, 45, and register withsimilarstops 39, 39, on the locomotive frame to limit the outwardmovement of the end cab. A draw barcouplingmember 46is provided at thetop of the end wall 40. The vfloor plate'35 is hinged at itsrear end toa transverse bar extension 36 of the main frame andis adapted to befolded up against the locomotive frame when the end cab is to vbetelescoped, being held in-the folded position by the end wall 4 0 whenthe latter` is in its innermost position. Support for the iloor plate 35when lowered is afforded by a lip or edge 37 `extending transverselyracross the lower end of the end plate 40 upon which the oorplate rests,thereby affording a supporting structure fory the motorman. y Y

Details of the controlling devices and locking means therefor willnow-be described:

Anormally uprioht hand lever 47 is mounted on the inner en ofa'transverse shaft.48 having bearing in a mounting frame 49 at one sideofthe locomotive frame, adjacent the shoulder 43 of the end cab.'- Atthe opposite end of said shaft 48 is mounted a downwardly extendingylever '50 to which is` connecteda longitudinally disposed connecting rod51 which at its opposite or rearwardyen'd is pivotally joined .to agearsector`28 so as to ro- -tate said sector, ,the latterbeingvmountedffor movement in 'a vertical plane on a transverse stubshaft 28al on they side frame 11, adjacent the forward end'of thecontriiller 16; i. Aubevel pinion=29 is keyed'to thgiforward endofthecontroller contact drum 17 and registers with the gear se ment 28,thereby providing means whereby t from the end cab. It will beunderstood that e locomotive may be controlled `the lever '50 extendsdownwardly in a plane parallell with the shoulder v"t3, rearwardlythereof when the end cabis extended, and 'outside of the marginal limitsof the frame member-11 and its cooperating extension .45.

Movement of the hand lever 47 forwardly if as it may clafims.

and downward gauses an op osito rearward movement or t met of the ever50 Wlxijcii pushing movementis exerted,y on the cote wardly, therebycausing rotation lbf/tha con troller drum in one direction. Movementot.

the hand lever 47Jrearwardly and upwardly, in a similar manner, causesthe opposite movement to take place.

Means are also provided' for locking fthe controller in the .ofpositionvwhen theA end cab is telescoped or in' its inoperative/position, thesame means bein likewise used to prevent accidental telescopmg of theend .,cab.

A. transversely disposed stop member isl pivotall mounted on alongitudinal axis to a crossar 31 of the locomotive frame, and comprisestwo portions, 32 and 33, being upper and lower, respectively, theportion-33 being of greater weight than 32.- The ivotal mountin of thestop 30 is arranged Just rearwardly o the shoulder 43,when the end cabis in the extended position. .When the end cab is in such position thestop member 30 assumes a vertical position, the lower portion 33extending below the upper mar in of the shoulder 43 and side wall 41thereo and in the same vertical lane with said shoulder, between saidshoul er and thev locomotive frame. Any sudden pushing movementl on theend cab causes the shoulder and portion 33y to contact, therebypreventing inward movement of the end cab. When it is desired totelescope the cab the stop 30 is` manually moved to a transverseposition, thereby releasing the cab, the ortion 82 Vthen extendsforwardly of the ever 47, while the portion 33 rides loosely on theupper marin of the sidewall 41. In order to free the ever 47, so thelocomotive may again be,

started, itis necessary to withdraw the end cab, whereb when the sidewall `has vbeen withdrawn. yond the shoulder 43,'the por- ,fd tion 33 isreleased and automatically drops -to its former vertical positie vAltlou h I have shownand described one formr in w ich myinvention may beembodied,
